In highly regulated industries like mining and commercial assaying, "good enough" data is a liability. OnLIMS provides the statistical rigor required to ensure that every analytical result is validated and auditable.
Technical QA/QC Capabilities
- Standard Management Define validation rules and track Material Reference Certifications (CRMs).
- Control Sample Tracking Automated monitoring of blanks, duplicates, and standards within every batch.
- Statistical Performance Real-time generation of Shewhart charts and precision/accuracy metrics.
- Automated Validation Workflow-integrated rule checking that flags outliers before certificate generation.
- Compliance Readiness Built-in audit trails and data integrity features aligned with ISO 17025.
These specialized tools help laboratories maintain data reliability while improving operational efficiency. OnLIMS transforms quality control from a bottleneck into a competitive technical advantage.
Real-time statistical QC at the point of capture
OnQC (the QA/QC engine, also referenced as OnLQC) interprets control data inside OnWSH, the worksheet where analysts capture results. Because QC status sits next to the data, there is no separate export-and-check step: the analyst sees the control outcome as each result is entered, and the supervisor reviews exceptions in context.
- Accuracy control charts Shewhart, X-Control, CUSUM and Thompson-Howarth charts plot CRM results against the certified value to track bias and detect drift.
- Precision plots Duplicate range and percent replication plots quantify reproducibility from duplicate pairs across the batch.
- Every QC sample type CRMs, blanks, duplicates and control samples are validated as part of each analytical run.
- Accountable release An out-of-limit result triggers a real-time alert and is blocked from approval until the analyst records a justification note.
Defensible release within an ISO 17025 workflow
Quality control only counts if the release decision is traceable. OnLAB manages the analytical lifecycle — Pending, Ready, Approved, Published — with results locked on publish under supervisor control. Every change is captured by a full field-level audit trail recording the old value, new value, user and timestamp, alongside system and login audit logs.
- Controlled lifecycle Results progress from Pending to Ready to Approved to Published, locked on publish under supervisor control.
- Role-based access Administrator, Manager, Supervisor, Technician and Client roles enforce who can review, approve and publish, with Active Directory single sign-on.
- Audit-ready records Field-level audit trail plus system and login logs provide a defensible record for ISO 17025 workflows.
- Reporting and export Automated Certificates of Analysis, with export to CSV, TXT, XLSX and XML for downstream systems and clients via the LabData portal.
Frequently asked questions
How does OnLIMS measure accuracy and precision?
Accuracy is evaluated as bias against the certified value of a reference material, plotted on Shewhart, X-Control, CUSUM and Thompson-Howarth control charts. Precision is evaluated from duplicates using duplicate range and percent replication plots.
What happens when a result falls outside its control limits?
OnLIMS raises a real-time out-of-limit alert and blocks the result from approval. The analyst must record a justification note before the result can move forward, and the action is written to the field-level audit trail.
Does OnLIMS support ISO 17025 laboratories?
Yes. OnLIMS is designed for and supports ISO 17025 workflows, with a controlled Pending to Ready to Approved to Published lifecycle, role-based access control and complete audit logging.
